Small step-by-step guide on how to install and run Windows 8 Developer Preview under VirtualBox.
Create the Virtual Machine
While the ISO downloads, open virtualbox and create a new virtual machine:
- Operating System: Microsoft Windows, Version: Windows 7;
- 2048MB Memory size
- Create a new Virtual Hard Disk, with at least 20GB – you can use “Fixed-size storage” (better performance, but uses more HDD space) or “Dynamically expanding storage” (a bit slower, but the .vdi file grows as necessary, using less HDD space);
- In the “System” group, under “Motherboard”, choose the “ICH9” chipset, enable “IO APIC” and “absolute pointing device”; under “Acceleration” enable “VT-x/AMD-v” and “Nested paging”;
- In “Display” enable 2D acceleration. Increase the video memory accordingly (~ 40MB);
- In “Storage”, under “IDE Controller”, in the “Empty” node choose the new Windows 8 ISO file – this will be the Boot DVD;
- In “Network” adjust the network settings: in my case i am using the “Bridge Adapter”;
Install Windows 8
Boot the VM. It may seem that it is hanged at boot, but it is not, just be patient; 10 to 20 seconds later, the Windows 8 logo will show up and the setup will boot normally. The setup process, in the first stages, is pretty straightforward – virtually the same as Windows 7.
In my system the setup took about 25(!) minutes to complete.
It’s not possible to install the VirtualBox Guest Additions, so the overall performance is not brilliant (no Graphics accel. is a big drawback…), but Windows 8 remains usable for testing purposes.
Specs: VirtualBox 4.0.12, running under Windows 7 64bit, Core2Duo 2.13.
